Overall this is a pretty good mag, as others have said it is plastic, but I've had no issues with its durability. It did have a feeding issue 1 time when it was bitter cold out, I just put a tiny bit of silicone lube on the feeding mechanism of the mag and it worked fine afterward.

Pros:
Large Capacity
Has been reliable for me

Cons:
The mag is quite a bit wider than a normal AK mag and looks a little funny hanging off of my otherwise realistic looking AK.
